Abstract

An anal patch comprising an absorbent pad ( 3 ) in a shape with two substantially parallel flat surfaces and a contact surface perpendicular to the flat surfaces, the area of the contact surface being smaller than each of the two parallel flat surfaces, an adhesive part, comprising an adhesive coated backing layer ( 4 ), having a central aperture ( 8 ) wherein at least a part of the contact surface of the absorbent pad is aligned with the aperture of the adhesive part.

Claims (18)

1. An anal patch comprising:

an absorbent pad provided with a contact surface; and

an adhesive coated backing layer having a central aperture, the backing layer attached to the absorbent pad at an area around a peripheral edge of the central aperture with the contact surface of the absorbent pad placed over the aperture and exposed through the aperture of the backing layer;

wherein the backing layer includes a flange that is unattached to the absorbent pad such that the flange is adapted to move independently of the absorbent pad;

wherein the absorbent pad is oriented substantially perpendicular to the area at which the absorbent pad is attached to the backing layer.

2. The anal patch according to claim 1 , wherein the absorbent pad comprises an impermeable cover layer on all surfaces, except on the contact surface of the absorbent pad that is aligned with the aperture of the adhesive coated backing layer.

3. The anal patch according to claim 1 , wherein the absorbent pad is wedge shaped.

4. The anal patch according to claim 1 , wherein main surfaces of the absorbent pad are curved.

5. The anal patch according to claim 1 , wherein the absorbent pad extends from the contact surface and away from the central aperture.

6. The anal patch according to claim 1 , wherein the aperture is surrounded by the adhesive coated backing layer.

7. The anal patch according to claim 1 , wherein the absorbent pad comprises an effluent impermeable cover layer and a filter attached to the cover layer.

8. The anal patch according to claim 1 , wherein the adhesive is covered by one or more release liners.

9. The anal patch according to claim 1 , further comprising:

a non-stick surface placed over the contact surface and within the central aperture.

10. The anal patch according to claim 9 , wherein the non-stick surface is a net.

11. The anal patch according to claim 1 , wherein the adhesive coated backing layer is only attached to the absorbent pad at the peripheral edge of the central aperture.

12. The anal patch according to claim 1 , wherein the flange comprises a first flange extending away from one of two substantially parallel flat surfaces and a second flange extending away from an other of the two substantially parallel flat surfaces.

13. The anal patch according to claim 1 , wherein the contact surface of the absorbent pad is adapted for contact with a surrounding area of an anal orifice of the user and the flange is adapted to move independently of the absorbent pad as the user moves.
